Arcee
Arcee is one of the most dangerous Autobots, but also possesses an ardent protective streak for her comrades. An expert in close-quarters combat and an equally effective sharpshooter, Arcee's level head belies a dynamic powehouse who's not to be underestimated in battle.

Barrage
Even among the evil Decepticons, Barrage's mercilessness is the stuff of legend. Not content to bask in a victory, this Insecticon would prefer to see his opponents and the battlefield burned to cinders and scattered to the winds.

Bombshell
Bombshell's devious cerebro-shells allow him to compromise the minds of his foes. He delights in warping their helpless perceptions and controlling their actions… often to disasrous results.

Bumblebee
Never afraid to charge into even the most daunting battles, Bumblebee will always fight for what's right!

The heart of a butterfly with the sting of a bee, Bumblebee is one of the most honorable, likable Autobots around. Not blessed with the towering stature or packed arsenal of some of his peers, Bee makes up for it with an incredible amount of heart, an unbreakable spirit, and a willingness to put himself in danger that's unmatched in the robot world.

Chop Shop
An Insecticon with a penchant for stealing anything that isn't rigorously secured, nothing gets Chop Shop's motors revving like a good heist.

Cosmos
Even the most effective combat squad is nothing without resources. That's why Cosmos may be one of the Autobots most valuable players. Capable of deep space travel and lone orbital operations, Cosmos takes on the unglamorous tasks of communications with aplomb.

Demolisher
.A Decepticon known for his unflinching loyalty, Demolisher is a determined soldier and a masterful battlefield tactician.

Dinobot Sludge
A gentle giant, Sludge may not be the sharpest tool in the Dinobots' shed, but he's a fearsome, powerful warrior whose strength should never be underestimated.

Dinobot Slug
Hot-tempered and brutally combative, Dinobot Slug's fire-breath has never met an opponent it wouldn't melt into slag.

Dinobot Snarl
Covered in the spikey armor of a Stegosaurus, Snarl's gloomy personality tends to keep his Autobot comrades at a tail's length. Luckily for them, the silver lining to this dark cloud is Snarl's love of a good battle.

Dinobot Swoop
The skybound Dinobot's chilling form and combat prowess often overshadow his good nature and friendly demeanor.

Flamewar
Warrior, scientist, and secret agent, the cunning Flamewar will serve any role necessary to help the Decepticons gain supremacy over the Autobots.

Hound
A consummate outdoorsman, Hound has taken like Earth like a duck to water, and he uses his bravery and tracking skills to defend its majesty at all costs.

Inferno
The first to charge into a fire or a firefight, Inferno's armored skin and ability to extinguish blazes and bad guys with equal effectiveness make him one of the coolest customers in the Autobots' ranks.

Ironhide
Ironhide is the most experienced, tough, and battle-hardened of all the Autobots. As such, he's one of Optimus Prime's most trusted and well-respected warriors. Grizzled and wise, Ironhide also prefers actions to words, having seen the best and the worst the universe is capable of.

Jetfire
A lone wolf dedicated to advancement via technological supremacy, Jetfire's cutting edge specs make him one of the fastest bots around, but his calculating nature and checkered past don't make him the most popular among his fellow Autobots.

Mirage
An Autobot debutante before the war, Mirage's ambivalence towards battle belies his abilities as a cunning intelligence operative and deadly long-range marksman.

Megatron
As the leader of the Decepticons, Megatron combines brute strength, military cunning, ruthlessness, and terror into one tyrannical being. He possesses a bottomless hunger for power and energy and won’t be stopped until the Autobots have been annihilated from the universe.

Nemesis Prime
The dark mirror image of Optimus Prime, Nemesis Prime is a nightmare foe for the Autobots. Possessing the combat accument and memories of Optimus, the only thing keeping the universe safe from his menace is the deep instability left behind by the brutal experiments that created him.

Optimus Prime
The paragon of Autobot leadership and virtue, you'll see a picture of Optimus Prime if you look up "leadership" in a Cybertronian dictionary.

A good leader is a symbol to their soldiers. In the hallowed annals of Autobot history, there may be no more legendary a paragon of virtue and military accumen than Optimus Prime.

Optimus Prime is the leader of the Autobots. He feels his role is the protection of all life, including Earth-life, and he fights fearlessly and unceasingly to defeat the Decepticons.

Ramjet
The most unexpectedly blunt weapon in the unfriendly skies, Ramjet lives up to his name at every opportunity, slamming into opponents at ferocious speeds in an attempt to knock them out of the air.

Red Alert
Being the Autobots' head of security doesn't make Red Alert a very cool customer, but when disaster strikes, he's a crucial team member. When disaster strikes, nothing gets past his sensors and no bot does a better job of making sure everyone knows something's amiss.

Sergeant Kup
A legendary Autobot veteran and the source of countless thrilling tales from his battlefield exploits. Kup is as gruff and tough as a bot can be, but delights in his elder statesman status, often regaling his young comrades with a good story of missions past.

Shockwave
In a world of machines, Shockwave is may be the most cold and calculating of them all. Fueled by logic and a disdain for emotion, he approaches the war for robot supremacy with terrifying precision and a total absence of mercy.

Skrapnel
This insidious Insecticon uses his antennae to control electrical devices and blast powerful bolts of electricity at his foes.

Starscream
The biggest thorn in Megatron's side may not be the Autobots, after all. It may be his own Air Commander!

Sunstorm
This high-flyer is a volatile container for a powerful fusion reactor. His frequent radiations and bizarre personality render him a bit of an oddity and a loner in the Decepticon ranks, but he's a fast, powerful bot and a problem for his enemies.
